SCCM: Reusing the same NIC for multiple PXE initiated deployments in System Center Configuration Manger OSD

Microsoft SCCM OSD support published a nice article about the subj:


You basically need to add MAC address of a docking station or USB NIC you use for multiple machines to SCCM Discovery exclusion via editing SCCM registry as described:

This can be done by opening Regedit on the site server and navigating to the following registry key:


followed by editing the registry value of:


This registry key value is a multi-string value that is the placeholder of the list of MAC addresses to be filtered. The registry key holds one MAC address per line in the following format:



Note the known computers should be introduced with GUID instead of MAC after that. Please read details in the article.

SCCM 2012: PXE boot fails with: PXE-53: No boot filename received

I recently work on a case when we need to configure PXE boot –enabled Distribution Point for SCCM 2012 clients. Server holding DP and clients are in different subnets, so the router should be configured with IP Helpers (aka DHCP relays) to forward BOOTP requests from bare-metal clients to the PXE DP.

Problem: We configured IP helper on the router, but  PXE clients got an error: PXE-E53: No boot filename received. Everything was working if we configured options 66 and 67 (PXE server IP and boot image name) on the Corp DHCP, but this way is not recommended by Microsoft.

Resolution: In addition to IP Helper we needed to configure bootp-gateway option on the router and set it with IP address of the router for desktop VLAN.
